The Timeout property indicates the length of time, in milliseconds, until the request times out and throws a WebException. The Timeout property affects only synchronous requests made with the GetResponse method. To time out asynchronous requests, use the Abort method.

Note

The WebRequest class is an abstract class. The actual behavior of WebRequest instances at run time is determined by the descendant class returned by the WebRequest::Create method. For more information about default values and exceptions, see the documentation for the descendant classes, such as HttpWebRequest and FileWebRequest.

// Create a new WebRequest Object to the mentioned URL.
WebRequest^ myWebRequest = WebRequest::Create( "http://www.contoso.com" );
Console::WriteLine( "\nThe Timeout time of the request before setting is : {0} milliseconds", myWebRequest->Timeout );
// Set the 'Timeout' property in Milliseconds.
myWebRequest->Timeout = 10000;
// This request will throw a WebException if it reaches the timeout limit// before it is able to fetch the resource.
WebResponse^ myWebResponse = myWebRequest->GetResponse();
